STANLEY M. KATTELL, OF SYRACUSE, NEW YORK, ASSIGNOR TO THE SHAV-RIIE SAFETY RAZOR CORPORATION, OF PATCHOGUE, NEW YORK, A CORPORATION OF DELAWARE.

SAFETY RAZOR.

Application filed October 7, 1922. Serial No. 593,129.

To all to ham it may concern Be it known that I, STANLEY M. KATTELL, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Safety Razors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in safety razors wherein a single edged blade is contained within a suitable holder and an adjustable guard is adapted to be applied to either side of the blade.

A principal object of this invention is to provide a razor of the character described wherein the guard member may be readily removed to permit suitable stropping the razor blade, and in the accomplishment of this object, to avoid use of movable or easily broken parts.

A further object is to provide a razor of the character set forth wherein the guard member is interchangeable and may be quickly applied upon either side of the blade without removing the blade from the holder.

Another object of this invention is to provide a razor of the character "described wherein means are provided to readily dislodge the guard member from the holding member.

Still another object is to provide a razor as described having a detachable guard member wherein means are provided for locking the said guard member upon the holder.

The above objects as well as others herein after set forth in the .s giecification and the claims, are attained by the device illustrated in the accompanying drawings in which Figure l. is a side view of the razor show ing all parts assembled;

Figure 2 is a side view from the opposite direction Figure 3 is a section along the lines 3-3 of Figure 1;

Figure 4 is an end view from the blade end of the device;

Figure 5 is a side view showing the guard memberin a position just prior to looking upon the holder or displacement therefrom;

Figure 6 is a fragmentary view, in perspective, showing the outer end of the blade and bolder, and,

Figure 7 is a view of the guard member showing the inner face thereof.

In the specific embodiment of the inveir tion illustrated in said drawings, the reference numeral 1 indicates a razor handle and 2, a razor blade holding member which is attached to the razor handle by the pivot 3. The end of the blade holding member away from the handle is channeled or grooved longitudinally from said end along one edge of the member, as at 4:, to receive a razor blade 5 which may be slid longitudinally therein and which fits snugly within the channel.

The guard member 6 is constructed with duplicate hooks 7, one at each end of the guard near the back edge of the same. The hooks are for attachment of the guard to the holding member, and by virtue of the hooks both being the same, the guard may be placed on either side of the blade according to whether the right or left side of the persons face is to be shaved.

To provide suitable means for permitting the hooks 7 to engage the holding member, I have shown a hole 8 in the holding member at a distance from the end of said member substantially equal to the length of the guard. One of the hooks 7 may then be engaged in the hole 8 from one side or the other of the holder and the guard then swung inwardly toward the holder as inclicated in Figure 5 so the other hook 7 will slidably engage the end of the holder. Preferably the end of said holder is knurled or otherwise roughened, as at 9, to provide frictional engagement with the hook which may also be roughened or knurled, as by 10, to increase the friction. The holder preferably has a shoulder 11. for limiting the position to which the guard may be swung on the holder. It will be obvious from the above, that the guard may very readily be hooked into the hole 8 at the proper side of the holder and the end swung quickly into position where it will remain until positively removed.

In the illustrations shown, the guard is placed, for what might be termed a right hand shave and the blade edge is used from one side only, but when it is desired to use the other side of the blade edge, the guard is dislodged and attached to the reverse side in the manner similar but reverse to that shown. The knurlings 9 and 10, operate as a locking means to hold the guard in posi tion against accidental dislodgment.

To facilitate the disengagement or dislodgment of the guard from the holder, a lip 12 is formed upon the guard and by pressing with the finger upon this lip the guard may be dislodged for displacement or removal. As a facilitating means for applying the guard to the holder, outstanding lugs or prongs 13, may be provided upon the guard at opposite ends thereof adjacent the edge thereof next the cutting edge of the blade. Means are also provided to adapt the holder to receive blades of slightly varying thickness and hold the same with the necessary rigidity. This result is obtained by slottingone or both side walls of the holder as at 14. thereby increasing its resilience. At the same time, sufiicient frictional contact is obtained upon the blade to retain it against sliding and the holder is of suitable strong material to prevent tilting of the blade. Upon removing the guard from the holder the blade may very readily be stro'pped and re-edged in the manner commonly employed for stropping ordinary razors;

Various-modifications and changes may be employed in the construction or use of my safety razor without departing from the spirit or scope of this invention and I do not wish to be understood as limiting myself except as set forth in the following claims when construed in the light of the prior art.

Having thus described my invention, 1 claim 1. A safety razor comprising a holding member having a transverse hole spaced from its end, and a reversible guard having duplicate hooks, one at each end, one of said hooks adapted to engage in said hole while the other frictionally engages the end of the holder.

2. A safety razor comprising a holding member having a hole spaced from its end, and a guard having a hook at one end for engagement in said hole and having a hook at its other end for engagement with said holder, the end of the holder and the inside of the hook being roughened to obtain fric tional contact therebetween.

3. In a safety razor, a holder having means for supporting a razor blade, said holder having means at one end for attachment to said holder and having a hook at its other end for engagement with the end of the holder, said hook being roughened at its inner side so as to obtain increased contact with the holder.

4. In a safety razor, a holder having means for supporting a razor blade, a guard for said blade, said guard having means at one end for attachment to said holder and having a hook; at its other end for engagement with the end of the holder the said end of the holder being roughened to obtain additional frictional contact between the holder and guard.

In testimony whereof I affix my signature.

STANLEY M. KATTELL.
